Does the car have a flash tune on it?

Good luck man. I'm having issues with stacking the JB4 with my BM3 tune as well. Not getting a lot of help on here either. :-(

I've been active on here for quite a few years. I can tell you this, before BMS branched out to 18 other vehicle platforms, troubleshooting and getting questions answered were second to none....

I'd try to ask over on the other forum for insight but if you mention the JB4, it's like saying you have an STD or something LOL. Don't get me wrong, I'm very happy with my BM3 tune, but the flexibility with the JB4 is an awesome addition to a flash tune. Once you get it working properly.....

Looks like DSC is kicking in and then you trigger a safety system.

Let's start with a lower map like map2 to evaluate a clean run first before going up.

Thanks Terry my map 6 is a custom map for my Bootmod3 e30 flash, I switched over to map 4 for logging only to check. I've attached that log of map 4.

I see a few things. Let's try this next.

Map7, enter 75 across the board on fuel bias to increase port injection mapping.

Have a thread? Normally the issue with BM3 is they set the target really high. So that might require a special JB4 side setting.

Last thread I saw from you was about fuel pressure connector not working on a used system? We need to get your hardware going too. If you have a tuning issue also post the details in the same thread so we can cehck that out.

Thank you Terry! but how do I adjust the fuel bias for map 7? I'm using the jb4 mobile app with the bluetooth connection for android. Also my e85 gauge doesn't work on the app, I don't have a ethanol setting under wmi nor a n20 map sensor category.

Settings > user adjustments

Fuel bias should be the middle column
